Question: Recently, my dog’s nighttime scratching is keeping both of us awake. Her fur seems dry and a bit dandruffy, and she also seems to be shedding more than usual. What can I do to help her?
Answer: Dogs itch for many different reasons, and sometimes, for no reason, and it’s not uncommon for the scratching to seem worse at night, when the house is quiet. Every dog’s got TO scratch some time, and that’s completely normal. But when a dog is incessantly licking, scratching, biting and chewing to the point of wounding herself, then scratching becomes a symptom of an underlying pathology.
Is It Dry Skin?
One common cause of itching is dry skin. If you live in a region with low humidity, it’s more likely that your dog will have dry skin, which is fairly easy to recognize. When you part your dog’s hair, you see flakes of dandruff in the undercoat, and the skin itself may be cracked and tough. The slightest stimulation of the skin—your gentlest touch—can provoke your dog to scratch violently.
Dry skin can be influenced not only by environmental factors, but also by diet. Commercial pet foods process out the good oils that contribute to healthy skin and a lustrous hair coat. Dry pet foods have an even more dehydrating effect on skin and hair and also stimulate increased thirst, which only partially compensates for the drying nature of these diets.
If you must feed dry foods, then by all means add digestive enzymes to your dog’s meals. In fact, digestive enzymes are good to use with any type of food. Enzymes improve the release of nutrients, and beneficial probiotic bacteria also assist in the digestive process. (Probiotics also help with allergies, as noted below.) A healthy digestive system absorbs fluids more readily from the food your dog eats, thus improving hydration and increasing the moisture levels of the skin and hair coat.
Another common cause of itchy skin is allergies. Allergies may make your dog’s skin dry, greasy, or slightly dry and oily, and are accompanied by frequent scratching, licking or chewing. We are seeing significantly more cases of allergic dogs than we have in the past; many veterinarians believe that we are experiencing an “allergy epidemic.” While the reasons for this allergy epidemic are uncertain, some of the theories put forth include the aggressive vaccination protocols that many dogs have been subjected to, poor breeding practices and the feeding of processed pet foods.
Whatever the cause, allergies are difficult to address. In the worst cases, afflicted dogs require strong (and potentially toxic) pharmaceuticals just to get some relief. Though allergies are rarely cured, early identification and intervention can keep them under control, and in some cases, can substantially diminish them.
Regardless of age, many dogs’ allergies are controlled by improving the quality of their diet, giving them high potency acidophilus cultures and high doses of fish oils; adding freshly milled flax seed; and, in some cases, giving them antihistamines. (It can take up to three months for this regimen to take effect; see sidebar for details and dosages.)
About 90% of allergic pets can be effectively controlled with the following treatments. Some dogs might only require a fatty acid supplement or a simple change in diet to keep their allergies under control, whereas, some animals may need to incorporate several or all of the following treatments to be effective. I will give treatment options for all three allergy types. Remember that many animals may have allergies to more than one allergen and may also have both food and atopic allergies.
